CysLT(1) antagonists are effective for a subset of patients with asthma; however, there has been no good way to predict a given patient's response. We examined the interaction between the clinical response to a cysLT(1) antagonist, pranlukast, and DNA sequence variant A(-444)C in leukotriene C(4) synthase (LTC(4) S) gene in Japanese patients with moderate(More)
Approximately 4% of the Japanese population genetically lack plasma platelet activating factor acetylhydrolase (PAF-AH) and show a higher prevalence of thromboembolic disease, but whether they are susceptible to another PAF-related disease, asthma, remains controversial. To determine the role of plasma PAF-AH in airway physiology, we performed PAF(More)
Prostaglandins and thromboxanes are important modulators of airway physiology. The synthesis of these mediators depends on two isoforms of cyclooxygenase (COX), constitutive COX-1 and inducible COX-2. COX-2 expression has been observed in various inflammatory diseases, but not all aspects of the expression and the role of COX-2 in conditions of allergic(More)
